{"id":"CVE-2026-63449","summary":"Suricata sip: large SIP message bodies can evade detection with frame keyword","details":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the SIP parser in rust/src/sip/parser.rs stores request and response body lengths in 16-bit fields. A SIP body larger than 65,536 bytes can truncate the length and prevent frame:request.body or frame:response.body from exposing the complete body to inspection, allowing content in the omitted portion to evade frame-based detection. This issue is fixed in version 8.0.6.","aliases":["GHSA-prqx-q74v-wxhv"],"modified":"2026-09-20T11:47:08.171683155Z","published":"2026-09-18T20:12:30.737Z","database_specific":{"cwe_ids":["CWE-197"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63449.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/OISF/suricata/releases/tag/suricata-8.0.6"},{"type":"WEB","url":"https://redmine.openinfosecfoundation.org/issues/8582"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63449.json"},{"type":"ADVISORY","url":"https://github.com/OISF/suricata/security/advisories/GHSA-prqx-q74v-wxhv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63449"},{"type":"FIX","url":"https://github.com/OISF/suricata/commit/499995bf0e5eab34b647ec1024ce65d72c411816"},{"type":"FIX","url":"https://github.com/OISF/suricata/commit/6f87930aff1e2294e46289cb9cbf4d96d79a209a"},{"type":"FIX","url":"https://github.com/OISF/suricata/pull/15807"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/oisf/suricata","events":[{"introduced":"9956286fb89f9cad9e9f95b99dc751f8666617b7"},{"fixed":"499995bf0e5eab34b647ec1024ce65d72c411816"},{"fixed":"6f87930aff1e2294e46289cb9cbf4d96d79a209a"},{"fixed":"4c28cc1b4ac64f48efdca6ce3e09748227a04a7e"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"8.0.0"},{"fixed":"8.0.6"}]}}],"versions":["suricata-8.0.5","suricata-8.0.4","suricata-8.0.3","suricata-8.0.2","suricata-8.0.1","suricata-8.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63449.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
